I'm not a case person myself but won't you be covering it up? And the fronts are all the same.
The silver and grey don't look so good where the 2 colors meet the front of the phone, black is way sleeker due to that imo.
I had an otterbox for a while, but now I'm thinking I'll buy the extra insurance so I don't need a case. I guess I'll see what the cases look like.
